Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 87,104,771, it is easier to work with a table - it's called factoring from the outside in.
We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.
| 1 | 87,104,771 | |
| -1 | -87,104,771 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 87,104,771.
Example:
1 x 87,104,771 = 87,104,771
and
-1 x -87,104,771 = 87,104,771
Notice both answers equal 87,104,771
With that explanation out of the way, let's continue. Next, we take the number 87,104,771 and divide it by 2:
87,104,771 ÷ 2 = 43,552,385.5
If the quotient is a whole number, then 2 and 43,552,385.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 87,104,771 | |
| -1 | -87,104,771 |
Now, we try dividing 87,104,771 by 3:
87,104,771 ÷ 3 = 29,034,923.6667
If the quotient is a whole number, then 3 and 29,034,923.6667 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 87,104,771 | |
| -1 | -87,104,771 |
Let's try dividing by 4:
87,104,771 ÷ 4 = 21,776,192.75
If the quotient is a whole number, then 4 and 21,776,192.75 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.
Here is what our table should look like at this step:
| 1 | 87,104,771 | |
| -1 | 87,104,771 |
If you did it right, you will end up with this table:
| 1 | 13 | 37 | 47 | 481 | 611 | 1,739 | 3,853 | 22,607 | 50,089 | 142,561 | 181,091 | 1,853,293 | 2,354,183 | 6,700,367 | 87,104,771 |
| -1 | -13 | -37 | -47 | -481 | -611 | -1,739 | -3,853 | -22,607 | -50,089 | -142,561 | -181,091 | -1,853,293 | -2,354,183 | -6,700,367 | -87,104,771 |
